Answer:

1. Elvis because his sales are average and less than 39 from the bottom and top.

Whitney H as she is not 6 away from the top and is average.

2. 465 / 5 = 93 which makes mean Elvis closest to the calculated mean.

3.  The first group would have the higher deviation as the numbers have a broader range before and after subtracting the mean and squaring each number.

4. Subtract the mean from each number. Square each number individually write on a new grid, to find the deviation.
